Description of drawings
Fig. 1 is the block diagram of the embodiment of mobile telemetering system.
Fig. 2 is the example chart according to the wireless signal strength contrast of the type of the information that will be sent out.
Embodiment
Along with vehicle enters and leave cellular broadband (or other is wireless) overlay area, the vehicle data of collection can interrupt off and on via the real-time Transmission of cellular broadband network.As example, the only part of designated vehicle test route can fall into the zone with cellular broadband service.Along with vehicle enters non-overlay area, any vehicle data of collecting in this non-overlay area can't be sent out.In case vehicle reenters the overlay area, the real-time Transmission of the vehicle data of collection can be restarted.Yet the data of collecting in non-overlay area also can need to be sent out.Bandwidth and/or signal intensity constraint condition can limit and/or retrain the real-time Transmission of the vehicle data of collection, and the transmission of the data of collecting in non-overlay area of buffer memory and/or file.
The embodiment disclosed herein can provide the mobile telemetering system that is configured to collect and send via Radio Transmission Technology (for example, cellular broadband, Wi-Fi, WiMax, satellite etc.) vehicle-relevant data.Particular system can detect the available scope of wireless transmission service.These systems can send the vehicle-relevant data of collection subsequently based on the available scope of wireless transmission service.As example, under the situation that certain minimum signal strength that provides can be used, the data of collection can be based on last in, first out by wireless transmission.Otherwise the data of collection can be filed and/or be stored.
Dissimilar vehicle-relevant datas can be collected by other system, and difference is located in the transmission of managing these data of different types.As example, particular vehicle information can be collected continuously (for example, one second once, and per two seconds one inferior), and other information of vehicles can be collected based on the generation of scheduled event.If signal intensity is greater than certain minimum threshold, then which information is the information (or trickle (trickle) information) of collecting continuously can be the information of collecting recently and being sent out based on.If signal intensity is greater than another threshold value, then based on the generation of incident (or event information) and the information that is collected can be sent out.
These threshold values can be depending on the size of the information that will be sent out: for example, the size of the information that is sent out is more little, and threshold value is low more; The size of the information that is sent out is big more, and threshold value is high more.
Can use several signal strength threshold in certain embodiments.For example, can set up minimum threshold, surpass described minimum threshold and send trickle information.Can set up second threshold value, surpass described second threshold value and send event information.Can set up the 3rd threshold value, surpass described the 3rd threshold value and send the event information that files.Can set up the 4th threshold value, surpass described the 4th threshold value and send the trickle information of filing.In this example, second threshold value is greater than minimum threshold, and the 3rd threshold value is greater than second threshold value, or the like.Other is arranged and scheme also is possible.
With reference to Fig. 1, the embodiment of motor vehicles 10 can comprise the data acquisition module of functionally arranging with radio data system 14 (DAM) 12.In this embodiment, data system 14 comprises modulator-demodular unit and cellular transceiver.Therefore, data system 14 can send to cellular antenna 16 with information from DAM 12 in a known way.In other embodiments, data system 14 can comprise and is used for sending and/or the known and/or appropriate module of the information of reception via Wi-Fi, WiMax, satellite etc.
In this embodiment, DAM 12 can collect customizing messages (trickle information) with assigned rate.That is to say that DAM 12 is observation particular vehicle correlation parameter during time period of one second for example, and in the ending of this time period, DAM 12 in record to each parameter buffer memory minimum value, maximal value and mean value (if available).Therefore, in this example the speed obtained of data be one second once.Yet, can use any suitable speed.
During next time period (for example, next second), DAM 12 observes the vehicle correlation parameter once more, and in the ending of this time period, DAM 12 carries out buffer memory to any change of minimum value, maximal value and the mean value of each parameter.As example, if in the ending of time t=1, minimum value, maximal value and mean value are respectively 0.5,1.5 and 1, then DAM 12 buffer memory minimum value 0.5, maximal value 1.5 and mean value 1.If in the ending of time t=2, minimum value, maximal value and mean value are respectively 0.4,1.6 and 1, then DAM 12 buffer memory minimum value 0.4, maximal value 1.6 and mean value null value.This allows will need less data during the hop of handling.Sustainable any appointment duration of above-mentioned steps.
DAM 12 also can based on specify and/or scheduled event collect customizing messages (event information).These appointments and/or scheduled event can comprise that designated parameter surpasses predetermined threshold (for example, coolant temperature surpasses 30 ℃, and car speed surpasses 70m.p.h etc.), vehicular events (such as, vehicle launch and/or stop) etc.
Event information can comprise any information that can use DAM 12, and can be buffered based on every incident and be file.Yet event information can be collected with the precision higher than trickle information (resolution).For example, event information can be collected with the hour range of 1ms, and as mentioned above, trickle information can be collected with the hour range of 1s.Certainly, can use any suitable technique and/or the scheme that is used for acquisition of information.
As explained above, vehicle 10 can enter and leave the zone by cellular antenna 16 services.As known in the art, data system 14 (for example, the modem portion of data system 14) can detect the wireless signal strength that is associated with the wireless signal that is received by data system 14.DAM 12 can use this signal strength information to determine that vehicle 10 is whether in the zone by cellular antenna 16 services.For example, if signal intensity is 0, then DAM 12 can determine that vehicle 10 does not have in the zone of service at cellular antenna 16.In so non-overlay area, DAM 12 can file the record of buffer memory and be a plurality of message files, and the incident file of any buffer memory that can file.If signal intensity is greater than 0, then DAM 12 can determine that vehicle 10 is in the zone by cellular antenna 16 services.In such overlay area, DAM 12 can make the record of buffer memory be sent out via data system 14 based on last in, first out.To discuss the transmission of the file of the incident file of buffer memory and/or file below in more detail.
The speed that DAM 12 makes data system 14 (for example, the antenna part of data system 14) send the record of buffer memory can equal the trickle data at least and obtain speed.Use the trickle data of above-mentioned example obtain speed be one second once.Therefore, DAM 12 can make data system 14 send the record of buffer memory at least with one second speed once.Yet, also can use other transfer rate.
See figures.1.and.2, the type of the information of transmission can be depending on the signal intensity that is detected by data system 14.For example, need only signal intensity greater than certain minimum threshold (for example, 5%), the trickle of buffer memory record just can be sent out.As long as signal intensity is greater than higher threshold value (for example, 20%), the incident file of buffer memory just can be sent out.As long as signal intensity is greater than another higher threshold value (for example, 40%), the incident file of file just can be sent out.As long as signal intensity is greater than high threshold (for example, 60%), the message file of file just can be sent out.
This scheme can be realized by attempting sending nearest trickle information based near real time by DAM 12.Yet, can use other threshold value and/or with the type of the information that is sent out according to wish.As example, certain threshold level can be depending on the size of the file that will be sent out.Above-mentioned example is listed 40% signal strength threshold, so that the incident file that files is sent out.Yet if the incident file of the file that will be sent out has the size less than certain threshold size, DAM 12 can reduce this threshold value (or selecting lower threshold value).Similarly, if the incident file of the file that will be sent out has the size greater than certain threshold size, DAM 12 this threshold value (or select higher threshold value) etc. that can raise then.Can similarly handle the threshold value that is associated with the out of Memory type.
Refer again to Fig. 1, can comprise server 32 and be configured to the subscriber computer 34 of the information on the access server 32 away from the position 30 of vehicle 10.Server 32 can be configured in a known way via the information of internet 36 acquisitions by cellular antenna 16 receptions.Server 32 can also be configured in a known way at being sent by data system 14 and at any record and/or file that server 32 receives, confirmation signal being sent out to be received by data system 14 via cellular antenna 16.That is to say, if data system 14 sends to cellular antenna 16 with specific file, and server 32 these specific files of reception, then server 32 will make the affirmation signal of indicating server 32 to receive this specific file be sent out via cellular antenna 16.
In a particular embodiment, receive affirmation signal with deleted record and/or file at server 32 in case received indication, DAM 12 just can make the file of the record of any buffer memory and/or file and/or any file deleted.
As those of ordinary skill is clear that, each of the file of buffer memory and the file of file can have the size that is associated with them.For example, the message file of some files can be greater than other file.The incident file of some buffer memorys can be less than other file etc.DAM 12 refers again to Fig. 1, no matter can make the file of buffer memory or the file that files be sent according to file size (for example, minimum to maximum) by data system 14.That is to say that under the signal intensity that provides made the situation that the incident file of buffer memory can be sent out, the incident file of minimum buffer memory will at first be sent.Similarly, under the situation that the feasible incident file that files of the signal intensity that provides can be sent out, the incident file of minimum file will at first be sent.
As those of ordinary skill is clear that, algorithm disclosed herein can be passed to the treating apparatus that can comprise any existing electronic control unit or special electronic control module in a variety of forms, and described many forms include but not limited to: permanent storage writes the information on the formula storage medium (such as the ROM device) and is stored in the information that can write on the formula storage medium (such as floppy disk, tape, CD, ram set, SD card and other magnetic medium and light medium) changeably non-.Described algorithm can also can be carried out object with software and realize.Perhaps, can use suitable nextport hardware component NextPort (such as, special IC (ASIC), state machine, controller or other nextport hardware component NextPort or device, the perhaps combination of hardware, software and fastener components) implement all or part of of described algorithm.
